If you believe Jesus Christ is the son of God, you are a Christian. The fact of the matter is a lot of people have done very bad things in the name of Christianity. Adolf Hitler was one of such people as was Anders Brevik was another. Only a small example of the tyrants of the tyranny known as Christianity.

There is no such thing as a true Christian, they are only supplying us with excuses for corruption. I'm disinterested in excuses and only interested in real justification.

Well not to say that they are all completely insane lol. But Christianity certainly does influence a lot of corruption. And when they write off this as "well those are not true Christians", its sort of like inaccurately saying that Christians are perfect or superior and could never do wrong.
